When investing companies find themselves in conflict over international investments, most prefer to resolve the dispute with the assistance of an arbitration lawyer under trusted international rules rather than in unfamiliar foreign courts. McMillan lawyers are experienced advocating for clients before a wide range of international arbitration tribunals. We have handled international arbitrations involving parties from all corners of the world, arising from international contracts in virtually all major industries.

We are one of few Canadian law firms to consistently be ranked among world’s top 100 international arbitration law firms, as selected by Global Arbitration Review. Many of our international arbitration lawyers have also been recognized by leading directories such as Chambers Global, Who’s Who Legal: Commercial Arbitration, Best Lawyers in Canada, Lexpert and Euromoney’s Guide to the Leading Experts in Commercial Arbitration.

When clients invest in emerging economies, McMillan’s international arbitration lawyers play a critical role, assisting companies whose investments are threatened by the actions of a host state. We also represent investors in arbitrations brought against states under a wide range of investment protection treaties, including the North American Free Trade Agreement, and other bilateral investment treaties.

McMillan’s international arbitration lawyers have helped Canada’s top business leaders succeed globally by representing them before arbitral tribunals established under the rules of all major Canadian, international and regional institutions; assisting clients with the design of arbitration provisions in commercial contracts; and advising on corporate structures to take advantage of investment treaty protections.
